Title: Elastic surface wave device
Inventor: YAMAZAKI OSAMU
IPC: H03H9/145
Filed: 1979-02-20
Abstract: PURPOSE:To reduce the insertion loss as well as the triple transit echo by distributing the two-way converter between the comb-line electrode unilateral converters. CONSTITUTION:When the high-frequency voltage is applied to connection terminals 18 and 19 of two-way converter 14, the elastic surface wave is excited and then propagated to both sides of converter 14. If unilateral converters 12 and 13 located at the both ends are distributed equidistantly from converter 14 at the center or either one of the unilateral converters is located at the position which is apart by the integer-fold value of the length of the elastic surface wave, the elastic surface wave excited by converter 14 can be received in a high efficiency. Also if the tuning is secured for converter 14, the elastic surface waves entering through both ends are offset to each other and never emerge at terminals 18 and 19. As a result, the reduction can be secured for the effect of the triple transit echo caused by the reflection among electrodes.

Title: Electronic component
Inventor: UCHIYAMA KENJIRO
IPC: H01C1/034
Filed: 1993-01-11
Abstract: PURPOSE:To enable mounting of components onto a printed board even when the total mounting area of components exceeds the mounting capacity of the printed board by integrating the electronic components, e.g. resistors, with an insulating film. CONSTITUTION:After lead pins 1a, 1b are connected with a thin stripe resistor 1 at the opposite ends thereof, thin synthetic resin films 2a, 2b, e.g. PVC films, are applied to the top and bottom faces of the resistor 1. It is then thermally fused thus integrating the resistor with the insulating films. Consequently, the thickness of electronic component can be reduced and when the electronic component is mounted on a printed board, mounting area for the electronic component can be reduced. Furthermore, it can be folded compactly and thereby packaging paper or securing tape can be saved at the time of transportation.

Abstract: PURPOSE:To secure safe running by controlling changing-over of a shift valve and a timing valve with a solenoid valve, and putting the spool of 1-2 shift valve into the second speed position when adjusting oil pressure is the lowest. CONSTITUTION:When a signal from an electronic control device 58 actuates a solenoid valve 56 to turn the No.1 oil pressure output condition into No.2 oil pressure output condition, only the spool 28 of a 2-3 shift valve 26 is changed over from No.1 to No.2 position, while the spool 42 of a 3-2 timing valve 40 is held in No.1 position. When No.3 oil pressure is put out, the spools 28, 42 of the two valves 26, 40 are both changed over to No.2 position, Accordingly the same speed change position is attained with No.2, No.3 oil pressures, but the condition of the timing valve 40 is different, and an appropriate speed change timing is obtained according to the degree of opening of a throttle valve, the car speed etc. Safe running is secured even at the time of failure in the solenoid valve 56 as long as such an arrangement is incorporated that the spool 12 of 1-2 shift valve 10 is put into No.2 speed position when the adjusting oil pressure is the lowest.

IPC: F02D29/02
Filed: 1988-01-29
Abstract: PURPOSE:To prevent lowering of drivability by detecting a decrease in load by load condition detecting means during constant speed control, and providing speed change ratio changing means for increasing a speed change ratio when a throttle valve reaches a designated opening close to the totally closing state. CONSTITUTION:When a decreases in load of an engine M3 is detected by load condition detecting means M11 and a throttle valve M1 reaches a designated opening close to the totally closing state during constant speed control, speed change control means M6 are driven by speed change ratio changing means M12 to increase the speed change ratio of automatic transmission M5. Accordingly, the application of an engine brake becomes stronger so as to lower the car velocity. When the car velocity is less than a preset value, output control means M8 are driven by constant speed control means M10 to increase opening of the throttle valve M1 and keep the speed of a vehicle M2 constant. By the above operation for increasing the opening of the throttle valve M1, the throttle valve M1 is kept from being totally closed, and the stop of fuel supply from a fuel supply valve M7 is not performed.
